JAMES G. GIBSON, OF PEORIA, ILLINOIS.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. J;2O,652, dated February 4, 1890. Applicationfiled February 14, 1889. Serial ITO-299,894. I (NoinodeL) To all whom it nuty concern.-

Be it known that L JAMES G. GIBSON, a citizen of the United States, residing at Peor1a 1n the county of Peoria and State of Illinols, have invented certain new and useful Improvements in Corn-Planters; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which-it" appertains to make and use the same.

' This invention relates to corn-planters in which the planting mechanism is driven from the axle of the supporting-wheels; and it consists in certain improvements in the construction of such machines, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan view of a corn-planter provided with my improvements. Fig. 2 is a side view of the same, one Wheel being removed. Figs. 3

and 4 illustrate a shifting-lever and its connections. Fig. 5 shows in section a slotted drum fast on the axle and a device which engages with the drum. Fig. 6 represents a retaining device, which is connected with the seed-bar.

A designatesthe side bars of the-frame of the planter, the same being mounted on the axle B, on which are the carrying-wheels O. The forward ends of the bars A are pivotally connected with a cross-beam D, on which are mounted the seed-boxes E, the rear ends of said bar's being connected by a curved bar or rod F.

To the cross-beam D under-each seed-box is made fast the standard of a share or cutter G, which forms a furrow in the soil, turning it in opposite directions from the center of the furrow. Back of each cutteris a spout H, which extends downward froma seedbox E, and at the rear of the spout the covering-shovels I are fixed in position to cover the seed dropped from the spout. The wheels 0, being in line with the cutters and spouts, press the soil over the seed after it is covered by the shovels I.

.1 indicates a slotted drum-cam, which is provided with an inclined or oblique slot 0,

against the cylinder, and the parts are secured together and to the rod 12 by a bolt and nut, the said rod fitting beween the flanges of the plate 0. The head thus formed, being partly within the slot a of the drum, oscillates as the drum revolves, and imparts a reciprocating movementto the rod 5.

Fixed to the rod 1) is a flanged plate cl, which is in the form of a shallow T-shaped vessel,

and is placed with the upper bar of the T form on and along the rod 6, with the stock extending forward, as seen in Fig. 1.

K indicates a standard, at the top of which is formed a stud e, the said standard being supported by an arm f, extendingfrom a side bar A of the frame. A slotted plate g is placed loosely on the standard, the stud e entering the slot, so that said plate hasa limited movement lengthwise. From the rear end of the plate 9 extends a rod h, the free end of which'is bent downward and rests in the flanged T-plate d. From the forward end of plate g extends another rod h, the free end of which extends through a perforated lug 2', which is fastened to a transverse bar L, which is the seed-bar, and extends under each of the seed-boxes of the planter. A footlever is is connected at its lower end with the standard K by a bolt or rod m, which passes through the lever, the standard, and the support f, and is secured by a nut 02. A stout tension-spring n is placed on the bolt m and bears against the bolt-head and the support f, holding the lever 7t close against the standard. At the point of connection of lever 7a with the standard the latter is provided with an annular flange or tubular projection 41 end of said lever fits over the tubular projection "a and has notches on its inner face, which are adapted to receive the projections n so that when the lever has been moved either forward or rearward it will be retained in position. The lever is connected with the slotted plate g by a bolt 0, which is passed through a slot in the lever, so that the said plate with its attached rods may be moved forward or rearward by means of the lever.

As will be seen, the reciprocating movement of the seed-bar is produced by the vibration of the rods h and 7t, which are carried by the plate g, such vibration being caused by the T-shaped vessel on the rod 1) engaging the red It, the bent end of which rests in said vessel. \Vhen the lever 70 is thrown forward, the rod h is drawn forward and its hook end is brought into the narrow forward part .2 of the vessel (1 in position to be engaged by said vessel as the rod 1) reciprocates; but when the lever k is thrown rearward the hook end of rod h is pushed to the rear part of the vessel d, where the latter is wide enough to allow the movement of rod 1) without engaging the rod h, and consequently there is no movement of the latter or of the seed-bar. An arm at is fastened to the seed-bar L and extends at right angles therefrom. Another arm 1) extends from the cross-beam D and is pivotally connected at its outer end by a bolt 19 with a bent fork 19 which straddles the arm m, as seen in Fig. 6. On the bolt 1 is placed a spiral spring, which presses against arm 19 and against a nut on the upper end of the bolt, so that the arm 1) and the fork p are held closely together. The adjoining surfaces of the arm 11 and fork p are formed like the adjoining surfaces of the lever 70 and standard K, the said arm 1) being provided with tubular and angular projections, and the fork 13 having notches to receive such angular projections, so that when the seed-bar in operation is thrown in one direction,the fork turning with it, no back movement of said bar will be caused by the jarring of the moving plantelx.

M indicates the drivers seat, which is supported by rods connected with the frame of the machine, a foot-rest N being secured to the draft-pole 0. At the rear of the machine a horizontal rod Q is loosely held by the curved arms P, which are fastened to the frame. To the rod are secured two scrapers R, each of which is held in the rear of one of the wheels 0, for the purpose hereinafter stated. A hand-lever S is pivoted on a cross-rod q, the ends of which extend in uprights carried by the side bars A, said lever being provided with a short arm a, which extends forward and is connected by a link 8 with an arm 3', which is fastened to the draft-pole. The lever S is also provided with a hook v, by which it may be connected with the drivers seat, the lever being moved backward. 'When the planter is in operation, the lever is disconnected from the seat and the scrapers R through the rod tand arm a are brought against the wheels C and serve to clear them of any dirt adhering. \Vhen the operation is discontinued, the lever S is hooked to the seat, the front part of the machine being thus lifted and the cutters and shovels raised from the ground, and the scrapers R are held in position away from the wheels G by the rod U, connected with the lever.

T indicates a rod one end of which is provided with a hook v' for its attachment in an eye v of the curved rod F at the rear of the frame. To the outer end of the rod T is secured a marking-board, which is provided with a point y, and said rod is connected by a cord y with one of the seedboxes E. This rod, when in position being connected with the curved rod F and by cord y with a seed-box, extends outward at right angles with the line of draft, with the marking-board resting on the ground, so that as the planter is drawn forward it will mark a line in the ground which will be parallel with the line of draft and serve as a guideline for the planter on its return across the field. The rod T is made of a certain length, so that the guide-line will be the same distance from the track of the nearer wheel as the distance between the two wheels of the planter.
